III IIIIII movement ofthe axle causes the upper ends heads 23 and and the cylinder move of the tubular sections 24 to engage the thus draw downward upon the disk 21 and downward upon the rods 20 and the'plunger 17, sol that here, though the movement of the body and the axle are in relatively opposite directions, yet the piston toward each other and the air cushion is compressed.. l thus secure a compression of the air cushion upon a relative movement of the body and axle in opposite directions.

In Fig. l 'of the namely, the usual frame beam, and in the drawings this frame beam 14 is not shown as bearing upon the member 21 but as engaging with this member 21 upon a relative depression of the body and a, relative elevation of the axle.V This gives a certain range of movement 'betore the iston commences to move inward upon a ownward movement of the body and an upward movement of the axle, but it is obvious that the body or the member le may rest directly upon the disk 21 and also that the lengths o the members 15, 22 and 24 may be altered so as -to secure a more immediate reactionof the shock absorber to the movement of the vehicle.

It is to be understood that the mechanism which l have shown in my drawings is purelyillustrative, as itis obvious that the invention may be embodied in many didst'- ent forms, depending upon the type of car to which the device is to be applied and the range of movement between the body and the axle. rods 15 and the cylinder 10 and between the section 24 and the section 22 permits small oscillations of the body and axle but as soon as large oscillations are set up, the air cushion operates to yicldingl resist the movement ofthe parts and cus ion the jolt which would otherwise be given to the car body. Thus while I have illustrated my invention in the accompanying drawings as used in conjunction with a vehicle spring, it is t0 be clearly understood that my improved shock absorber may be employed in lieu of or as a substitute for such springs, the latter being entirely dispensed with.

Having described my invention, what I claim is y 1. The com ination with two elements movable toward or away from each other, of a shock absorber comprising a cylinder and a plunger acting against an air cushion in the cylinder` on one side of the plunger, and means for ca'usn a relative movement of the plunger `ai'rldicy inder to compress the an cushion -upon a movement of the elen i' e ts either toward each other-or away from ,ledcli other.

drawingsthe body of the vehicle is represented by one element thereof,

The sliding connection between the Leuvense 2 The combination with a vehicle including a body and an axle, of a shock absorber including a cylinder arranged to be moved toward the body by the axle, a pi ston operating against an air cushion in said cylinder between the axle and piston, means arranged to be directly engaged by the body for moving the piston toward the axle, whereby upon relative movementof the axle and body toward each other the air cushionv is compressed, and means connecting the axle with the piston and the body with the cylinder to cause a. relative movement of the piston and cylinder to. compress the air cushion upon u relative movement of the axle and body away from each other.

3. The combination with relativel other, o a shock absorber disposed between said elements and comprising two compressiin'g members operating against an air cushion, means for causing a relative movement or the compressin' members to compress the cushion upon a relative movement of the cle ments toward each other, and means `for causing a relative movement ofthe compressing members to compress the air cushion upon a relative 'movement of the elements away `from each other.

4. The combination with two elementsA movable toward or from euch other, of s. shock absorber disposed between the ele 'lli y ltwo elements movable toward or from each ments and comprisin' a cylinder abuttedagainst one of said e ements and movable with it toward the other element' a pistom'aJ ieldable .cushion disposed in the cylinder i ody between the piston and said e ement,

and means arranged to be abutted by the 'other element for moving the piston toward the lirst named element whereby upon relative movement of the elements toward each other the cushionis compressed, operative connections between the other element und the cylinder and having sliding lost motion engagement with the cylinder, and means extending from the first named element and having sliding lost motion connection with the piston, whereby a relative movement of the elements away from each other causes a relative movement of the piston and cylinder te compress the cushion.

5. The com ination with a vehicle including a body an an axle, of a shock absorber comprising a cy in'der, a `piston operating against an air cushion in said cylinder, and means connecting' the piston to the axle and the cylinder to the body to causen .relative movement of the piston and cylinder to com press the air cushion upon a relative move-- ment of the vbody and axle either toward or away from each other.

6. The combination with two elements relatively movable toward and away from each other, of a shock absorber disposed between said elements and comprising a cylinneonato f der and a piston operating against an airl cushion in said cylinder, dlrect connections between one of said elements and the cylinder and between the other of said 4elements and the piston to cause relativey causing a relative movement between the piston and cylinder to compress the air @zieltel ion upon relative movement ot the elemente toward each other after a predetermined entent of relative movement of said elemente toward each other, and means. to canse relative movement between the comprension members to compress' theairensbionnpon n continued relative movement ot theelementn away from each other after a predetermined extent of relative movement ot said elemente away from each other.
